When a plane crash-lands in the arctic, eight young survivors step from the wreckage expecting to see nothing but ice and snow. Instead they find themselves lost in a strange jungle with no way to get home and little hope of rescue. Food is running out. Water is scarce. And the jungle is full of threats unlike anything the survivors have ever seen before—from razor-beaked shredder birds to carnivorous vines and much, much worse. With danger at every turn, these eight kids must learn to work together to survive. But cliques and rivalries threaten to tear them apart. And not everyone will make it out of the jungle alive.

The survivors have made it out of the jungle, but they may be sorry they ever left when they stumble upon a whole new ecosystem, populated with entirely new threats. And the greatest threat of all may come from within. Because one of the kids is changing... The seven-book series begun by #1 New York Times bestseller Scott Westerfeld only gets bigger and bolder under the frenzied imagination of bestselling, critically acclaimed author Jennifer A. Nielsen!
